V 3 Claims.

This invention relates to an interchangeable sign more particularly intended for use as a highway sign. 7 v

The principal object of the invention is to provide a sign construction which can be quickly and easily assembled at the time of erection to give any desired indication or information and which, when assembled, will securely lock itscomponent parts together to prevent unauthorized tampering.

Other objects and advantages reside in the detail construction of the invention, which is .designed for simplicity, economy, and efficiency. These will become more apparent from the following description.

In the following detailed description of the invention reference is had to the accompanying drawing which forms a part thereof. Like numerals refer to like. parts in all views of the drawing and throughout the description.

In the drawing:-

Fig. 1 is a perspective view illustrating a typical sign constructed according to this invention.

Fig. 2 is a plan view, thereof. 7 I

Fig. 3 is an enlarged vertical section, taken on the line 33, Fig. 2.

Fig. 4 is a fragmentary rear elevation of the front sign plate. Q

Fig. 5 is a detail view of one of the letters.

Fig.6 is a fragmentary view illustrating an alternate form of the invention. V

vThe invention comprises a perforated front sign plate It), the entire surface of which contains-perforations I I regularly spaced over its surface. The letters of the sign, indicated at 12, are pref erably formed of sheet metal with rearwardly extending ears l3 spaced so as to enter the spaced perforations ll. v

The rear of the sign is closed by means of two back plates I4 and IS. The outer extremities of the plates and I5 are bent to form hook like edges which enclose the side edges of the front plate Ill as shown at Hi.

The inner extremities of the plates l4 and I5 overlap each other as shown in Fig. 2, so that attachment bolts l6 may be passed through all three plates to attach the sign to a supporting post or standard [8 as illustrated.

The sign is formed by selecting the desired letters and passing the tongues l3 through the perforations to give the desired letter spacing and arrangement. The tongues are then bent downwardly as shown in Fig. 4.

The plates l4 and [5 are hooked over the edges j of the plate "I and the bolts l6 are tightened to clamp the entire assemble in place. The bolts l6 clamp the back plates l4 and I5 tightly against the tongues 13 to lock the letters in position and to prevent unauthorized removal thereof.

The extremity of the bolt It may be riveted into its nut to prevent removal of the bolts.

In the usual installation, the perforations H in the face ll! are allowed to remain exposed, as shown in' Fig. 1. If desired, however, the face -may be painted with a thick viscous paint which will flow into and fill the perforations, leaving. a

substantially smooth back ground surface, as shown at [9, in Fig. 6.

The letters maybe made any desired heighth.

It is only essential that they terminate in align- 15 ment with the spaces of the horizontal rows of perforations. The letters illustrated are three spaceshigh. They could, however, be one or more spaces as desired.

While a specific form of the improvement has been described and illustrated herein, it is desired to be understood that the same may be varied, within the scope of the appended claims,v without departing from the spirit of the invention. Having thus described theinvention, what 'is claimed desired secured by Letters Patent is 1. An interchangeable sign comprising: a perforated face plate; metal letter members; tongues formed integrally with said letter members and projecting rearwardly from said letter members through the perforations in said face plate; a backing plate secured to said face plate; and means for drawing said backing plate against said face plate to clamp said tongues againstthe latter.

2. An interchangeable sign comprising: a perforated face plate; letter members; tongues projecting rearwardly from said letter members through the perforations in said face plate; a backing plate; a hooked edge on said backing plate for enclosing the edge of said face plate; 4 and means for clamping said backing plate against said face plate so as to lock said tongues in place therein.

V 3. An interchangeable sign comprising: a perforated face plate; letter members; tongues projecting rearwardly from said letter members through the perforations in said face plate; a pair of backing plates; hooked edges on said backing plate for engaging the side edges of said face plate, saidbacking plates overlapping each other; and clamping means for clamping the overlapped edges of said backing plate to the back of said face plate. y ROYAL A.
